My whole life I have lived with a huge dent in my left butt cheek when i asked my mother what happened to me she told me that I was born with it since i was born with pneumonia it makes sense that I may have received a kenalog shot as a newborn, I am 37 now and just had plastic surgery and the doctor administered 100cc of fat (fat transfer) and was still not able to fill in the dimple cause it was too deep. now I have to pay for the procedure again in order for him to complete filling the dimple ($3000.00), I hope he plans on giving me a discount but my butt feels fuller and the dimple is only on the surface now, and much less noticeable than before.
